A SARM is S23 (Selective Androgen Receptor Modulator).
It was made by changing the chemical structure of the C-6 compound. S23 is essentially a better variant of C-6, with increased bioavailability and binding affinity.
S23 has a high bioavailability of up to 96 percent and one of the greatest binding affinities of any SARM on the market, equivalent to LGD-4033.
S23, along with LGD-4033, is the only SARM that is a complete agonist of the androgen receptor. As a result, S23 is very suppressive, equivalent to steroid suppression in terms of Testosterone suppression. It’s worth noting that S23 induced infertility in every rat it was tested on, demonstrating its potency.
S23, like other SARMs, functions in a similar fashion to anabolic steroids, with the exception that SARMs are selective. This implies that, unlike steroids, this SARM will solely target androgen receptors in muscle tissue and will not have the same adverse effects as steroids, which also impact receptors in the prostate.
This indicates that S23 and other SARMs will function similarly to steroids but posing less risks. SARMs are, on average, far weaker than steroids, yet this chemical is extremely powerful and equivalent to steroids in strength. S23 and YK11 are the most powerful SARMs currently available.
